Childhood Adversity And Sexual Risk Taking In College: Pathways Through Alcohol Use, Sarah Josephine Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Exposure to adverse childhood experiences (ACEs) is associated with a host of negative outcomes throughout the lifespan including engagement in health-risk behaviors such as sexual risk taking and alcohol consumption (Dube et al., 2006; Negriff et al., 2015; Zaso et al., 2021). Additionally, sexual risk-taking and alcohol use commonly co-occur (Certain et al., 2009; Downing-Matibag & Geisinger, 2009). This may be especially true during the transition to college, in which many young adults have increased access to substances, increased autonomy, and an expanded network of peers. Thus, the present study examined the relationship between ACEs, alcohol use, and sexual risk …

Factors Related To Adolescent Anger In Appalachia: Implications For Violence Prevention, Rosalina Mills

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background. Adolescent health outcomes are vitally important for public health. One such outcome includes adolescent violence, a persistent and prevalent public health issue in the United States. Adolescent violence in rural areas is particularly understudied and some measures of rural violence are underreported compared to violence metrics in urban areas. A key risk factor for adolescent violence, is anger. By examining known key risk factors for adolescent anger through a primary prevention and socioecological perspective, it may be possible to reduce or prevent downstream violence in adolescence and later adulthood. Identifying specific systemic, environmental, and interpersonal factors related to anger …

Benefits And Barriers Of Using Prefilled Precedex Syringes In The Operating Room: A Cost Comparison, Ashley White

Graduate Theses, Dissertations, and Problem Reports (ETD)

According to a report published by the Institute of Medicine, at least 44,000 and possibly up to 98,000 Americans die each year because of medical errors in hospitals. More than 7,000 of those deaths are from medication errors alone (Stucki et al., 2013). Anesthesia providers in the operating room (OR) are at even greater risk to commit medication errors due to their easy access to medications and their autonomy to make independent choices for medication administration. A small rural community hospital in Pennsylvania lacks a protocol for Precedex preparation. Evidence-based research show the benefit of prefilled ready-to-administer syringes, but the …

4d Epr Oximetry Imaging For 4d Bioprinting And Tissue Engineering, Sajad Sarvari

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bioprinting, akin to 3D printing, employs cell-laden hydrogels such as GelMA (Gelatine Methacrylate) and Alginate instead of plastic or resin to create biological structures. The printing process followed by subsequent tissue maturation is known as 4D bioprinting, where the fourth dimension is time. Ensuring adequate and consistent oxygen, O2, supply within 3D bioprint volume over the entire maturation period process is crucial, as even transient hypoxia can impact cellular behavior and phenotypes. However, printing of fully developed vasculature remains an unresolved technical challenge. Several approaches to chemically (peroxides) or biologically (photosynthesis) generate oxygen during bioprint maturation have been proposed. However, …

Biology And Ecology Of Neonectria Magnoliae And Neonectria Punicea, Two Understudied Neonectria Species In West Virginia, Hannah Marie Petronek

Graduate Theses, Dissertations, and Problem Reports (ETD)

The family Nectriaceae includes numerous phytopathogenic fungi that cause canker diseases on both angiosperm and conifer hosts worldwide. Numerous Neonectria spp. cause cankers on hardwoods and conifers in North America, but their roles in contributing to tree decline and mortality outside of beech bark disease are largely understudied. One such pathogen, Neonectria magnoliae, causes perennial cankers on two native hosts in central Appalachia: Fraser magnolia (Magnolia fraseri) and tulip-poplar (Liriodendron tulipifera). We also recently confirmed N. magnoliae from non-native star magnolia (Magnolia stellata) in West Virginia. Both native hosts occur in the central …

Sexual Identity And Homophily: The Powerful Role Of Sexual Identity For Romantic Partner Selection, Lee Thorpe Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the role of sexual identity on homophily, and its effects on romantic partner selection. The principle of homophily states that individuals tend to befriend and seek romantic partners who are most similar to themselves based on certain social characteristics (i.e., birds of a feather flock together). The majority of the homophily literature focuses on heterosexual friendships and coupling. Recently, homophily research has included sexual identity in their analyses. However, recent studies have only investigated friendship formation/bonds for lesbians and describing certain racial coupling types for individuals based on their sexual identity. I fill the lacuna in research …

Short Episodes But Fast Friends: Examining The Effects Of Parasocial Relationship Quality On Mediated Intergenerational Contact In Grace And Frankie, Alysse C. Baker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Building on the foundations of intergroup contact theory (Allport, 1954), the parasocial contact hypothesis (Schiappa et al., 2005), and Harwood’s Contact Space (2010), this dissertation advances the existing literature on how intergenerational contact with media characters can improve young adults’ willingness to engage with older adults. Specifically, this study examines the effects of intergroup contact quality on the parasocial contact process. Episodes of the TV sitcom about older adult women, Grace and Frankie, were edited to create both a high contact quality condition and a low contact quality condition. The high contact quality condition was a montage that showed viewers …

Influence Of Scaling And Root Planing With Minocycline Microspheres On Clinical Outcomes Of Patients With Periodontitis, Nupoor Sandeep Kulkarni

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Scaling and root planning (SRP) has been established as a “gold-standard” non-surgical initial treatment for periodontitis. Along with SRP, some systemic adjuncts like systemic antibiotics were used in the past to gain maximum benefits of SRP by reducing the need for further periodontal surgeries. Due to some drawbacks of systemic antibiotic use, like “transient antibiotic resistance”, “non-adherence” and “insufficient concentrations in the periodontal pockets to be clinically effective”, there was a shift towards the use of local antibiotic adjuncts to SRP like minocycline, tetracycline, chlorhexidine etc. Minocycline is a semi-synthetic tetracycline derivative which is available in a powder form, …

Clinical Significance Of Gutta Percha Variability, Alex R. Pancake

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The production of gutta percha points as root canal therapy filling materials vary from hand processing to machine processing with a range of acceptable levels of error (tolerance). Similarly, endodontic files manufactured to complement corresponding gutta percha points exhibit specified levels of tolerance. Investigations into the consistency among manufacturers of files and gutta percha points is limited. The aim of this study is to see how variability in apical gauge and taper of gutta percha points affected the clinical performance during cone try in. The null hypothesis of this study is that there is no difference in two gutta …

Slope Stability Below Historic Pre-Law Mine Benches In The Northern Coalfields Of West Virginia, Muhammad Ali

Graduate Theses, Dissertations, and Problem Reports (ETD)

ABSTRACT

Slope stability below historic pre-law mine benches in the northern coalfields of West Virginia

Muhammad Ali

Slope failures and landslides are commonly occurring geohazards in the state of West Virginia and in the Appalachian region due to weak geologic strata, steep slopes, a humid climate, geologically recent river incision, and human landscape modifications. Historic surface mining has resulted in large-scale landscape alterations. Surface mining conducted before the Surface Mine Control and Reclamation Act (SMCRA) of 1977 did not require reclamation to approximate original contour; as a result, remnant highwalls and mine benches are common throughout the state and region. …

Exploring Physical Activity Promotion And Implementation Within Inclusive Post-Secondary Education Programs: A Mixed-Methods Design, Shannon P. Zimmerman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adults with intellectual and developmental disabilities (IDD) exhibit lower physical activity levels compared to their non-disabled counterparts, with only 23% of U.S. adults with IDD engaging in the recommended 60 minutes per day of moderate-to-vigorous physical activity. Inclusive Post-Secondary Education (IPSE) programs in the U.S. offer an opportunity to promote physical activity and address the critically low physical activity levels. Few IPSE programs have formalized physical activity courses, warranting an evaluation and development of the national curriculum in this area. This study expands on previous work by examining current physical activity promotion strategies at both the program and course levels. …

Implementation Of Bayesian Statistics To Answer Diverse Engineering Questions: Applications In Cancer Immunology And Engineering Education, Anika C. Pirkey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Quantitative Systems Pharmacology (QSP) refers to a mechanistic modeling approach used for assessing potential therapeutics by linking the molecular and cellular level mechanisms of the disease and therapeutic to the system-wide dynamics and clinical endpoints relevant to the disease. Although the field of QSP is still in its relative infancy, the mathematical methodology employed to predict the kinetics of these systems are not new and can be applied to a wide variety of systems. For instance, similar to QSP’s goal of guiding the development of novel therapeutics for various disease states, there exists a need to develop novel interventions in …

Immune system function is critical to maintaining the health and increasing productivity of cattle, affecting both their growth and their disease resistance. In an efficient immune system, the liver assumes an integral function in detoxification and metabolic processes and contributes substantially to overall production and immunity. In this study, we evaluated the hepatic mRNA expression of genes involved in innate and adaptive immunity in crossbred beef steers with either a positive or negative residual body weight gain (RADG). Positive-RADG beef steers (n = 8; RADG = 0.76 kg/d) and negative-RADG beef steers (n = 8; RADG = -0.64 kg/d) were …

Sex, Drugs, And Tbi: The Effects Of Sex Hormones And Trkb Activation On Alcohol-Related Behavior Following A Traumatic Brain Injury, Robin B. Oliverio

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traumatic brain injury (TBI) and alcohol use disorder (AUD) exhibit a bidirectional relationship: AUD increases the risk of incurring a TBI and, inversely, a history of TBI increases the risk of future AUD. The second portion of this relationship has not been as thoroughly investigated. Our lab previously demonstrated that a juvenile TBI significantly increases alcohol self-administration in females compared to uninjured females and the injured females developed a conditioned place preference (CPP) for ethanol. Given this stark sex difference, this dissertation will examine the mechanism through which this occurred by investigating how manipulations of sex steroids might affect this …

Characterizing 4,4’-Methylene Diphenyl Diisocyanate Exposure In Primary Human Epidermal Keratinocytes: A Multi-Omics Approach, Brandon F. Law

Graduate Theses, Dissertations, and Problem Reports (ETD)

Exploring the routes of exposure and biological fate of 4,4’-methylene diphenyl diisocyanate (MDI) has been a challenge for many years. Occupational exposure to MDI can result in the development of occupational asthma (MDI-OA) which results in loss of productivity, large economic costs, and costs to the individual worker. Initially, it was thought that respiratory exposure to MDI was the most likely route leading to MDI-OA. Industries utilizing MDI have been successful at controlling airborne concentrations according to industrial hygiene assessment and newly diagnosed cases of MDI-OA decreased and plateaued. New research suggests that dermal exposures to MDI may explain this …

Genetic Knowledge And Causal Beliefs: Implications For Health Behavior In Clinical And Non-Clinical Samples, Jamey T. Brumbaugh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Objective: As the genomic era in healthcare continues to surge, it is vital to examine genetically-related psychological concepts, such as genetic knowledge and genetic causal beliefs, in genetically relevant clinical groups. Parents /caregivers of children born with cleft lip and/or palate represent a population whose knowledge and beliefs about genetics may be influenced by their frequent utilization of genetically-related healthcare services (e.g., genetic testing and genetic counseling). To date, little is known about how such beliefs vary across disease types. Even less is known regarding how disease-specific genetic causal beliefs relate to perceived behavioral control for disease development. Method: A …

The Role Of Synaptic Zinc Signaling In Excitatory Circuits Of The Mouse Auditory Cortex, Philip T R Bender

Graduate Theses, Dissertations, and Problem Reports (ETD)

Synaptic zinc signaling modulates synaptic activity and is present in specific populations of cortical neurons, suggesting that synaptic zinc contributes to the diversity of intracortical synaptic microcircuits and their functional specificity. The pool of chelatable synaptic zinc is controlled by the zinc transport protein ZnT3, a protein which functions by moving free zinc into glutamatergic presynaptic vesicles, from which it is co-released with glutamate during synaptic transmission. Once synaptic zinc is released within the synaptic cleft, it acts on glutamate receptors on the post-synaptic spine, including ionotropic NMDA and AMPA receptors. While the inhibitory function of zinc on NMDA receptors …

Taking The Red Pill: A Content Analysis Of Ambivalent Sexism And Precarious Manhood In Alpha Male Podcasts, Madalen Lea Fields

Graduate Theses, Dissertations, and Problem Reports (ETD)

Podcasts have become increasingly popular across various platforms (e.g., Spotify or Apple podcasts). A more recent trend is the emergence of “alpha male” podcasts. The goal of these podcasts is to instruct young men how to stop being “betas” and on achieving “alpha male” status. These podcasts are a subset of the manosphere, a term used to describe media focused especially on hegemonic masculinity, which is characterized by their promotion of misogynistic beliefs and sexist rhetoric. Drawing upon social science research, three forms of sexism (i.e., ambivalent sexism, precarious manhood and violence against women) serve as analytical frameworks for understanding …

Life Cycle Impacts Of Hardwood Forest Resources For Sustainable Bioenergy And Bioproducts In The Eastern United States, Jinghan Zhao

Graduate Theses, Dissertations, and Problem Reports (ETD)

A life-cycle impact assessment of hardwood resources across the eastern United States was conducted based on the life-cycle inventory data for hardwood forest resource management and was integrated with the Forest Vegetation Simulator (FVS). This integration allowed for the analysis of forest carbon dynamics in the four subregions: northeast (NE), mid-Atlantic (MA), southeast (SE), and northcentral (NC). The system boundary was selected to be consistent with the A1 module (extraction and upstream production) required by an Environmental Product Declaration (EPD) for wood products. The results indicated that uneven-aged management (UA) yielded higher carbon stocks than even-aged management (EA) across all …

Development Of Dynamic Mass-Energy-Thermodynamics Constrained Hybrid Neural Network Models For Process Systems Applications, Angan Mukherjee

Graduate Theses, Dissertations, and Problem Reports (ETD)

First-principles models can provide very good predictions even for cases when there are no data at all, or data are limited in certain range of operating conditions, or for cases where data collection is infeasible. However, the development of accurate first-principles models for complex nonlinear dynamic systems can be time consuming, computationally expensive, and may be infeasible for certain systems due to lack of sufficient knowledge (information). It is also challenging to adapt first-principles models for time-varying systems. Furthermore, it can be difficult, if not impossible, to develop accurate models for some complex phenomena that are poorly understood. On the …
